This paper presents an efficient technique for human motion recognition; in particular, it is focused on labeling a movement as a walking or running displacement, which are the most frequent type of locomotion. The proposed technique consists of two stages and is based on the study of feature points' trajectories. The first stage detects peaks and valleys of points' trajectories, which are used on the second stage to discern whether the movement corresponds to a walking or a running
